DSCR Loan Calculator

A DSCR loan (Debt Service Coverage Ratio loan) qualifies you based on what the property earns — not your W-2 income, tax returns, or personal debt-to-income ratio. Lenders divide your gross monthly rent by the total monthly payment (PITIA) to get a single ratio. If it clears their threshold, you're approved. Enter your numbers to see your DSCR and whether you'd pass the standard lender cutoffs.

How DSCR Is Calculated for Residential Investment Property Loans

For 1–4 unit residential DSCR loans (the non-QM "investor DSCR" products used in most portfolio-scale REI financing), lenders use a simplified formula — different from the commercial real estate version:

Unlike the commercial real estate formula (Net Operating Income ÷ Annual Debt Service), residential DSCR lenders do not deduct vacancy or operating expenses from the numerator. They use the gross market rent shown on an appraisal or an executed lease. This means the quality of your rent documentation matters — a below-market lease can hurt your DSCR even if actual market rents would qualify.

DSCR Thresholds: What Lenders Typically Require

There is no regulatory minimum DSCR for investment property loans — requirements vary by lender, program, property type, LTV, and credit score. These ranges reflect typical non-QM DSCR lender requirements as of 2026:

Other typical DSCR loan requirements (vary by lender and program):

• Down payment: 20–25% for 1-unit SFR; 25–30% for 2–4 unit properties
• Maximum LTV: 75–80% for SFR; 70–75% for 2–4 unit properties
• Credit score: 660–700 minimum at most lenders; 680+ for best pricing
• Rate premium: typically 0.5–1.5% above conventional, depending on DSCR, LTV, and credit
• Personal income: not required — no W-2s, no tax returns, no personal DTI calculation
• Entity closing: many DSCR lenders allow purchase in an LLC name, unlike conventional Fannie/Freddie loans
• Property types: SFR, 2–4 unit, warrantable condos; some lenders extend to 5–10 unit small multifamily

When DSCR Loans Make Sense for Real Estate Investors

A DSCR loan trades a higher rate for dramatically simpler qualification. That tradeoff is worth it in specific scenarios:

• Self-employed investors with complex returns. If you're a real estate professional with significant depreciation deductions, cost segregation write-offs, and LLC pass-through losses, your Schedule E income may look much lower than your actual cash flow — disqualifying you for conventional financing even when the property itself is profitable. A DSCR loan ignores your personal return entirely. See how the cost segregation tax strategy creates exactly this situation.
• High personal DTI from existing mortgages. Conventional Fannie Mae guidelines limit total household debt-to-income, and once you own multiple financed properties, the aggregate payment load typically pushes past 43–45%. DSCR loans use the property's income, not your personal DTI, so there's no portfolio-size ceiling on how many you can finance this way.
• LLC or entity purchases. Conventional Fannie/Freddie loans require the borrower to be an individual. DSCR loans often allow purchase directly in an LLC — critical for investors structuring their portfolio by entity type for asset protection and estate planning. See our guide on LLC and entity structure for real estate investors.
• Short-term rentals (Airbnb/VRBO). Some DSCR lenders now underwrite on STR income, using AirDNA or Mashvisor rental income estimates rather than a standard long-term lease. A DSCR loan can make STR financing accessible when conventional products won't touch it. See our short-term rental tax guide for how STR income works alongside this financing.
• Scaling a portfolio with the BRRRR strategy. When executing a BRRRR cycle, the cash-out refinance step typically uses a DSCR loan — qualifying on the stabilized rental income of the rehabbed property. This lets you extract most or all of your initial capital without personal income qualification, then repeat.

DSCR Loans and Tax Planning: What Most Investors Miss

DSCR loans and REI tax strategy interact in ways that a generalist advisor typically doesn't see — because lending and tax planning are usually handled by different advisors who don't talk to each other.

• The depreciation and tax math diverge by design. A DSCR loan says "this property qualifies because rent covers PITIA." Your Schedule E may simultaneously show a tax loss — driven by straight-line depreciation (27.5 years) and OBBBA 100% bonus depreciation on cost segregated components. This divergence is a feature: the lender doesn't care about your Schedule E, and your tax advisor can use the losses against other income (if you qualify for REPS or the STR loophole).
• Cash-out refinancing via DSCR is tax-free. When you pull equity out of a stabilized rental with a DSCR cash-out refinance, there is no taxable event — no realization, no gain recognition. Your depreciation basis stays unchanged, your mortgage interest deduction grows, and you have capital to deploy into the next acquisition. See the full mechanics in our cash-out refinance tax guide.
• Entity structure affects both financing and taxes simultaneously. An LLC helps on both fronts — cleaner DSCR underwriting and asset protection. But S-corp elections for rental portfolios can be problematic: they limit the REPS grouping election and create self-employment tax complications. The right entity structure requires understanding both the lender's requirements and the IRS's rules at the same time.
• REPS plus DSCR financing creates maximum leverage. If your spouse qualifies for Real Estate Professional Status, cost segregation losses on DSCR-financed properties can be deducted against W-2 income immediately rather than suspended as passive losses. A fee-only advisor who understands both the two-part REPS test and the DSCR loan mechanics can structure purchases to maximize this combined benefit. Use the REPS calculator to estimate the value of unlocking these losses.
